'lG tNlTlNG DEVICE FOR GAS-BURNERS.

SPECIFICATION forming part of Letters Patent No. 631,267, dated August15, 1899.

" Application filed May 16, 1899. Serial No. 716,981. (No model.)

7 New York in the county and State of New York, have-invented a new anduseful Improvementin Igniting Devices for Gas-Burners; and ldo herebydeclare that the following is a full, clear, and exact description ofthe same.

My invention relates particularly to the kind of igniting devices forgas-burners illustrated in United States Letters Patent to A1 fred J.Sterne, dated August 23, 1898, No. 009,749, in which the platinumigniter is movable to and from the gas-jet, so that after ignition ofthe jet the igniter will not be exposed to the injurious efiects of theflame. The igniter may be normally held away from the jet by gravity orby a spring and moved into igniting position by hand, as illustrated,for the sake of example, in .said Letters Patent No. 609,749, or theigniter may be caused to move automatically to and from the flame by thesimple heating and expansive action of the flame on a thermostat inoperative connection with the movable igniter, as illustrated in anapplication for patent filed by.

Alfred J. Sterne aforesaid, March 6, 1899,

Serial No. 707,853.

The object of my invention is to simplify and improve the latterautomatic form of igniting device; and I attain this end by the meanshereinafter described, and.illustrated in the accompanying drawings, inwhich the same parts are designated by like letters in all the figures.

Figure 1 is an enlarged side view of an igniting device for gas-burnersembodying my improvements, the igniter being in igniting position. Fig.2 is a reverse side view of the same, the igniter being shown removedfrom the path of the jet and the upper part of the burner being brokenout to better disclose the construction. Fig. 3 is a side view taken atright angles to that of Fig. 1. Fig. 4 is a plan view.

In the drawings, a designates the burnerpillar, and Z; the jet orificeor orifices, the form of burner here illustrated being a standard BrayUnion-jet burner, although my invent ion islikewise applicable toabat-wing,

shown in the aforesaid Letters Patent No.

609,749 and application Serial No. 707 ,853. It is self-evident that thefine platinum wires may be in the form of a single wound Wire orplatinum gauze and maybe placed in contact with either the upper andlower or front surface of the platinized body 2', or both, as may bedesired and according. to the type of burner-tip used. The simple styleof wiring here shown has been found preferable for the Union-jet burnerhere illustrated. The igniter-lever f is by preference formed withapartialcounterbalance m to make its motion more steady.

To the bracket-arm e opposite that behind which the igniter moves ispivoted, by a pin 1), an intermediate lever 0, having a stop q for thelever f, the lower end of which lever 0 I engage with the igniter-leverf near the pivot Z of the latter by forming a tapering recess n in theigniter-lever to receive the end of the lever 0, the opposite sides ofthe end of the lever 0 acting as shoulders against the opposite sides,as bearings of the recess n when the lever o is moved to swing theigniter-lever and igniter positively both to and from the jet. The upperarm of the lever o is connected, close to the pivot 1), bya pin or rivetr, to one end of a thermostatic bar t, which crosses the edge of thegas-jet and is immovably connected, as by a rivet or pin, at itsopposite end to the opposite arm 6 of the bracket "If, so that theignitor being normally in igniting position over the jet-orilice, asindi cated in Fig. 1, the gas will be automatically ignited as soon asturned on. The flame will then quickly heat and expand the thermostaticbar it, which is made thin for that purpose, and swing the intermediatelever 0 so as to throw the igniter-lever and igniter to the position(indicated in Fig. 2) away from at the same time exposing both. sides ofthe.

bar to the direct action of the flame,- and thus causing it to expandquickly.

The engagement illustrated between the i gniter-lever f and-thethermostat-actuated lever or part 0 in .both directions insures thepositive outward throw of the igniter when the flame'is ignited whetherthe igniter-lever moves stiffly ornot and in whatever position theburneris mounted, either vertical or horizontal or inclined a resultwhich cannot be accomplished by the action of gravity alone and which isan exceedingly important feature of my invention,for if the igniter doesnot move out of the flame its efficiency is soon destroyed, as is wellknown. Further, by mounting the igniter-lever fand the intermediatelever 0 at or by opposite ends of the thermostatic bar t, as shown, saidlevers do.

not interfere with or unnecessarily limit the motion of each other,andat the same time both swing between the bracket (1 and the burner andare thus covered and protected by the bracket d and the theremostaticbar t, which latter can therefore be made of the full length necessarytoaccomplish the requisite movement of the igniter.

By this important improvement I effect in practice a movement of theigniter nearly half an inch from the jet, the importance of which inpreserving the igniter from the heat of the flame is well understood,and I accomplish this without carrying the bracket or any parts belowthe usual groove of the Bray Union-jet burner shown, thus leaving ampleroom for applying the pliers thereto in screwing the burner'on or ofitthe fixture.

Iclaim as my invention- 1. In a gas-1i ghterto be attached to a burner,a thermostatic bar a transverse section of whichis located in the pathof the gas-jet and lies approximately e'dgewise toward the jetorifice soas not to materially obstruct the flow of gas, in combination with anigniter and means whereby the thermostatic bar moves the igniter to andfrom the jet.

' 2. Inagas-lighter to be attachedtoa'burner, the combination with anigniter, a movable support carrying the igniter and having bearin gsrespectively for positively projecting the igniter into and positivelyretracting it from the jet, a thermostat and a part actuated by thethermostat having shoulders respectively to engage saidigniter-projecting and igniterretracting bearings. Y

3. In a gas-lighter to be attached to a burner, the combination with anigniter, a pivoted lever carrying the igniter, an intermediate isver,which positively projects into the jet and positively retracts from thejet the igniterlever, and a thermostat in operative connection with theintermediate lever.

4 4. In a gas-lighter'to be attached to a burner, the combination withan igniter, a pivoted lever carrying the igniter and formed with arecess in its edge, an intermediate lever having an end entering andengaging said recess,

and a thermostat in operative connection with I 'said intermediatelever.

5. In a gas-lighter to be attached to a burner, the combination with athermostatic bar crossing the jet, an intermediate lever pivotallyconnected to one end of said thermostatic bar, an igniter, and a pivotedlever arrying the igniter by the opposite fixed end of the thermostaticbar, said intermediate lever acting on said igniter-lever. I

In testimony whereof I have hereunto set my hand the 15th day of May,1890.
